﻿<p>An <i>IfcOffsetCurveByDistances</i> is a curve defined by a list of offsets along its <i>BasisCurve</i>. 
If only one offset is provided, it indicates a constant offset along the extents of the basis curve.

<p>Figure 2 illustrates eight instances of <i>IfcOffsetCurveByDistances</i> (in green) defined relative to an <i>IfcAlignmentCurve</i> (in blue).</p>
